To all whom itl may concernf Efe it known that wey-EMORY H. COPEN- dmva and WALTER .Ce vm, citizens of the United States of America, residing at Dunlevj, in the countv of Washington and State Aof vennsylvania, ave/invented certain new and useful im rovem'epts in Roller-Skates, of which the fo lowing-is a specification, reference being had thereon to the accompanying drawing.

This invention relatosY to roller skates. and more particularly to the wheel of a'skate.

The rim portions 10 and Mwave i somewhat similar to the clencher typc'of tire fastener, said portions providing a'lcircumferential dove-tail shaped groove for receiving a dove-tail sha ed tongue 12 of a resilient tire 13. preferably constructed from 1 rubber. The hub portion 9 of the inner part l or disk 7 extends into the race or socket 3.

In the ball race or socket 3 is mounted a plu,

and

com lished by using rubber tired wheels ball earings, the construction of these wheels of comparatively few being our invention.

'We construct a roller skate wheel of two metallic arts or disks braced and stamped to provi e hub portions and rim portions, the parts of the wheel being fixed upon an axle, whereby the rim portions will firmly gri a resilient tire. l

hc detail construction entering into our invention will be presently described and then speciiically pointed out in the appended claims.

In the drawings: Figure 1 is an elevation of a'wheel constructed in accordance with our invention, Fig. .2 is a vertical sectional view of a wheel as mounted upon the axle ofa-skate, Fig; 3 is an elevation of the outer art or disk of the wheel, and Fig. 4 is a simiar view 'of the inner part or disk.

In the accompanying'drawings, 1 designates a portion of a skate having an axle bearing2 rovided with ball races or sockets 3.

Revolu )lv mounted in the bearing 2 is an axle 4 having threaded ends 5. Mounted upon the threaded ends of theaxle are our improved wheels, each wheel comprising an outer art or disk 6 and an inner part or disk 7. T iese parts or disks are formed with hub portions 8 and 9, and with rim portions 10 of the axle 4, we em loy a nut 16.

lt will be observe( that our wheel consists arts that can be easilT l and quickly assemb ed and disassemble when it is desired to renew the tires.

We reserve the right to make such changes in the details of construction as are permissi ble by the appended claims.

Having now described our invention what we claim as new, 1s

The combination with a roller skate bearing, and an axle extending-therethrough, of wheels fixed upon the ends of said axle, each wheel comprising an outer part and an inner i part, ball bearings arranged between said skate bearing and the inner parts 'of said wheels, each part having a hub portion and a rim portion, the rim portions of said wheels providing a circumferential dove-tail shaped groove, a resilient tire fitting upon said rim and having` a dove-tail shaped tongue engaging in the groove )rovided therefor, substanti ally as described.

ln testimony whereof we aflix our signatures in the presence of two witnesses.
